This invention relates to pyrotechnics. and

-more particularly. to pyrotechnical devices adapted to be ignited and subsequently thrown in the air manually so as to produce balls of fire ofdiiierent colors and of great brilliance. I

The invention-consists of tablets made .up in desired sizes and consisting of. ingredients. which will burn vividly with a predetermined color whenever the tablets are scraped upon a striker of special'compos'ition. 7 In the accompanying drawings has been shown the preferred form-of the invention. In said drawings: Figure 1 is a perspec-- tive View of a box used for packaging the de-f vices; and Fig. 2 is a perspective-view of one of said devices. e The composition. of the tablets is as 'fol-.

.lows

For a green light,

Chlorate of barium 12 ounces.

Sugar of milk "2 ounces.
